Definitions

  • the invention relates to a vibration damper for machine bearings or the like, with a lower part which has a vessel with a filling of a viscous liquid, with an upper part which projects into the liquid from above with a plunger, the plunger in the liquid for braking of vibration deflections is arranged simultaneously in all directions, and with at least one non-positively arranged spring between the lower part and the upper part and without contact with the liquid.
  • Machines often have to be stored elastically.
  • a heavy foundation block is usually placed under the machine, which is supported on elastic bearings.
  • a plunger connected to the foundation block and immersed in a viscous liquid can be arranged as a damping device. With such an arrangement, vibration deflections in all directions can be braked simultaneously.
  • the plunger can be bell-shaped, for example.
  • the vibration damper can also be arranged next to a spring assembly. The object of the invention is to look for a particularly space-saving arrangement of the vibration damper next to one or more spring elements.
  • the solution to the problem is characterized in that at least one prestressed spring is provided entirely within the walls of the plunger, that at least one plunger projecting between the walls of the plunger is arranged as an abutment for the spring, and that one between the lower part and the upper part Height-adjustable mounting device is provided, at least one screw nut - bolt arrangement being operable from the side in the installed state of the vibration damper.
  • a preferred embodiment of the invention also provides for the height-adjustable mounting device to be arranged between the walls of the plunger, an opening being provided in the wall of the plunger for actuating the screw nut / bolt arrangement.
  • screw nut-bolt arrangement is designed to be removable in the installed state of the vibration damper.
  • screw connections bayonet locks and anchor channels are also possible.
  • Fig. 1 shows a schematic section through a vibration damper according to an embodiment of the invention.
  • the vibration damper shown in FIG. 1 has a lower part 1 with a vessel 15, which is partially filled with a damping fluid 3.
  • the upper part 2 is connected to the machine foundation, not shown, and projects with a plunger 4 into the liquid 3 from above.
  • the plunger 4 has an opening on the underside.
  • a stamp 17 protrudes beyond the liquid level.
  • the stamp 17 carries a spring 6.
  • the spring 6 and the stamp 17 are arranged coaxially with the plunger 4.
  • An intermediate plate rests on the spring 6 and is welded inside the plunger.
  • a screw bolt 10 is arranged axially in the spring 6 and protrudes upward from the punch 17 and penetrates an opening in the welded-in intermediate plate.
  • the screw bolt 10 carries a screw nut 11 above the welded-in intermediate plate, the spring 6 being compressible by tightening the screw nut 11.
  • An opening 14 is provided in the wall of the plunger 4 in order to be able to actuate the screw nut / bolt arrangement 10, 11.
